Question
Block 1 (0.5 kg) travels with an initial velocity of [ 40i ] + [ 40j ] m/s and then collides with block 2 (0.5 kg) traveling with an initial velocity of [-40i] + [-40j] m/s.
After the collision, block 1 has a final momentum of [10i] + [-10j] kg*m/s. Assume that no external forces are present and therefore the momentum for the system of blocks is conserved.
What are the final kinetic energies of block 1, block 2, and the system of blocks?
Block 1: ?
Block 2: ?
System of blocks: ?
